This is a great point, I dont think its possible to have a bad outer crust and a good bottom, any one ever had this?
If not, I think we can simplify the question to does a good crust make or break a pizza

First, as if those are the only two options lmao. If Trump loses in 2020 it wont be some great awakening on the American public. He won big in the electoral vote, but the margins were very slim in those swing states, and that was the worst candidate in history he was going up against. Second, the democrats, by not having Hillary run, by default should do better. The real question is, how many people has Trump been able to sway since he has been in office and with this booming economy?
As for the second or part, stop being so afraid and stop lumping all the people who support our president into one group. The majority of the people would expect him to do as the others before him did (well minus the spying on the party's opposition and the sabotaging of the incoming admin)
